[Q] 3 Mic holes on the backshell? - HTC Sensation

Regarding the 3 small holes on the back of the Sensation.
My guess is 2 mics for stereo recording with video and one for noise cancellation for calls.
Any case that blocks these, like the TPU from Amzer, would be a fail.
Is that the purpose of the 3 small holes on the backshell?

As far as I can tell they are for noise cancellation, but sounds feasible to be for recordings.

I thought they are there for the antennas....

Should be easy to figure out. I would but I don't have a Sensation yet.
Block one with something like a piece of tape. Record a video and see if you loose a channel. Repeat the same process for the other 2. If you loose right audio on one, left audio on another an nothing on the third, first two would be for stereo audio and 3rd for noise cancellation.

Antenna! Take the cover off and lose all signal... The hole are how the metal tags are connected to the case, kind of like riveted to the case. Looks like one deliberate hole near the speaker though

Ok. Of course we know the antennas are built into the backshell.
Although, have you ever seen a phone with holes for the antenna?

if you look at the pics at the bottom of this review it'll confirm that their for the rivets holding the antenna contacts. also seems the US version has 1 more contact point than the EU version, by the speaker.

my question is where would the second mic be?

Yup I can confirm the there are two holes that hold the connectors for the antenna (or at least the two coppery parts on the cover. The one near the speaker is just a hole, with plastic underneath it, can't say for sure if this is for a second mic that makes the video stereo..

in the link I posted you can see on the US version that one is also used for an antenna connection. I wonder why the US version has 1 more connection than the EU one.

even the standard HTC produced Sensation rubber cover I bought from the TMO store has all those holes covered except for the one near the camera lense. If I had to guess, I'd say the other holes are purely for the antenna anchors, while the anchor for the lense is also a hole for a mic. That one could certainly be for noise cancellation during phone calls while doubling as a mic for the right stereo channel

If you take off the back cover you can see where every hole is, there is a corresponding antenna anchor point... Why is this in debate?

6 holes in the backcover...
There are 6 holes total in the back cover of the T-Mo version of the HTS Sensation. I can confirm that the rubber cover I bought at a T-Mo store covers every one of those holes except for the one above the camera lens.
Taking the cover off I can see most of them are just anchor connections for the antenna contacts.

Because US one is 4G, maybe?

It's not really 4G, it's HSPA+ like the EU. Yay marketing

I spoke to HTC support and they clarified that obviously they are there for the antennas and also as air vents. The one above the camera and at the very bottom are mics. 2 for stereo recording.
They did say that all holes should be uncovered. Ironic, since the Body Glove case I bought at TMo covers up 4 of the holes, while many online I've noticed do indeed leave those hole uncovered.

Interesting about the air vents. I also have the Body Glove case as well and all the other cases at T-mobile have all the holes covered except the Mic above the camera.
I believe the case mate case actually covers every hole.

5 holes on back cover?

So I've been trying to figure out what all the holes on the back are for. I'm sure one is a Mic but what about the rest? Thanks

The one at the very bottom is a mic hole The 2 towards the bottom and the 3 one the top are rivet holes for the antenna connections holes but the one on the very top also acts as a hole for the stereo mic and noise cancellation. .

The 2 holes towards the bottom of the case seem unnecessary, leading me to believe that they could potentially be a water detection system. In the event that the phone gets dropped in water, these two holes would be some of the first areas to get wet, it would be pretty easy to detect a short between the two pins and disable the electronics inside if such a situation is detected, possibly saving your device from permanent damage.
Now I haven't tested this theory, mainly because I wouldn't want the device to log such a situation if that is how it works, but it would be relatively simple to test if anyone is willing to give it a go .
Most holes on back are where the copper connectors are under the cover..
Breathing holes I assume..
this topic has been covered a plethora of times!

Exactly...
I contacted HTC the day I got this phone....
Straight from the horses mouth....they are antenna rivets AND vent holes.
why is that ??? why holes ?? i havnt seen this sh*t on any other phone!!!!
thats ugly

And this is why I suggested that perhaps they may be specifically designed for water detection, it would be trivial to have the hardware shut itself off if there is no resistance between the two leads to prevent permanent water damage... Just my two cents.
so, couldn't someone put a paper clip or needle in there whilst the cover is on the phone to see if it turns it off?

Cases without proper holes cutouts..important?

Hello,
I want to buy a sensation case but it does not have the proper hole cutcuts on the back. The only cutouts the case has are the camera and the speaker.
if any of you are using a case with only these 2 cutouts, could you tell me if phone signal, 4g signal, mic, speaker, etc or anything else are affected?
greatly appreciated
i havent had a problem with them after on week of use, but just to be safe, i drilled holes where they should be

thanks for the reply, but if you drilled the holes then your case does have all the cutouts
it does now, but for the first week, i didnt have any issues...
i just did it cuz i was bored, and more as a precaution just in case...
mind you i never used the gps or wifi w/o holes...but i bought the 2 pack, one black (drilled), one opaque white (stock)...if you want, i can check the performance, but as it stands, there was no difference...
ive heard that all cases w/o holes are going to be discontinued, but that may have just been verbal diareah in the sensation thread :/
The only sensible answer is it depends on the case material. For any given case the only way to know is to try it. If it works then fine. If not, then drill holes if they're covered.
HTC says the holes should be uncovered, but none of us know exactly why. For a mic it's pretty obvious. For the others who knows. But drilling is easy and cheap, so for most cases a fix shouldn't be a problem.

I haven't seen a diagram showing the function of each one. Some are mics, either for input or noise cancellation. Others are likely antenna related. It's hard to imagine that HTC would go to the trouble of putting them there if they don't serve a useful purpose. Covering some or all may not cause big problems, but it's not likely to help either.
I have the official Tmobile silicone case and it doesn't have any cutout for the little holes...and it seems to be just fine.

I think I have the same case. Except mine does have one hole cutout above the camera.
Here's my observations that I posted in another thread:
moto211 said:
I've been noticing that most of the cases that are available only have the hole above the camera, even the ones sold by T-Mobile. So, it got me wondering, do the other holes serve any purpose? I took the back cover off and can immediately tell that the hole above the camera serves a purpose since it has a grommeted pass through in the inside housing. So, its good that every case I've seen has that hole cut out. The other four holes have no pass through and appear to only be there as rivet/mount points for the antenna contacts. So, after seeing that, I'm less concerned that even reputable manufacturers like otterbox are not including the other four holes that seemingly serve no active function.

The hole above camera is noise cancelling mic,that is the only important hole,so I had to drill it on my Case Mate Tough.They were the first proper company with hard case for Sensation,so they rushed a little bit with design,others like Otterbox and Seidio are making cases with that hole only.
Guys, EM radiation passes through silicone and plastic. There should be no need for holes on those materials. If you had a case made of metal, then you would need MORE than a hole anyways as EM radiation doesnt radiate in rays...Go into your bathroom and close the door. Plenty of material to be in the way of the EM radiation that is your signal. Still can make calls?
Also, there is no noise cancellation mic. There is no noise cancellation at all on this phone. The second mic is for stereo sound recording. I know alot of you wont agree, but looking up the specs, I found no mention of noise cancellation. (Only stereo sound recording).
If there were noise cancellation, people wouldnt complain about me being in the wind while talking to them. ;-)
Matt
Hmm if i'm not mistaken, two of them are for ventilation, one for noise cancellation mic, and the rest are for the antennas, the one for antennas has no use though, its only there to fasten the connectors.

Replacement GPS antennas/Flash covers?

I'm asking this because my GPS is frankly awful and I accidentally broke the GPS cover by melting it when solder was being put on the existing contacts.
Does anyone know where to get the Inspire 4G GPS covers? The Desire HD ones are nearly identical, but they lack the hole for the noise canceling microphone.
When the Inspire first came out there were issues with the covers and HTC was shipping them out for free. Do a search in the forum. Contact HTC and tell them your covers are trashed.
I have no experience with this supplier...

Those are different. The cover I'm looking for is where the LED flash is. You have to pop it out with a tool reaching into the battery compartment.
I bought a set of the 3 covers on the phone, hopefully the GPS cover is the right one and has the hole for a noise-cancelling mic.

I'm frankly not even sure if the Desire HD variant of the GPS cover is made in such a way that permits this to be done.
Just did some looking around and some experimentation. I think this is going to be the best course of action for an OEM-looking hole:
1. Find a paper clip that will cleanly go through the existing noise canceling hole. It shouldn't be too thin, but just about right.
2. Straighten out the paperclip so you get a nice straight section to work with.
3. Get a lighter or a gas stove and heat up the paper clip for a few seconds to get the straight section heated up enough to let you punch through the plastic without melting it completely.
4. There's a hole in the clear plastic where the LED flash connects to the black plastic, where the Inspire has a hole that goes cleanly through for it's noise canceling mic. Try to drive the paper clip wire clear through the hole, and make it straight. Hopefully there's enough heat for you to get a clean, smooth hole that looks like OEM.
I've taken a look at the dremel tools I have, and they are all definitely way too big for making a hole like this.

[Q] Aluminum Battery/Sim/Camera Cover

Hello Guys,
I was loking for hours to find Aluminum Covers for the DHD to replace the plastic parts but wasn't able to find them (if they even exist).
I only know that HTC never officially released them.
But since I saw the MAO Method they used on the One S I wanted the same for my DHD
Does anyone know a shop where I can find these covers made of aluminum?
Thanks

You mean the doors? Won't find them because the clips to hold them in place wont function being made out of aluminum. Thus why only the immobile parts are made of it. If that is not what you are talking about, ignore me Not to mention the signal loss of grounded aluminum over the antennas would be crazy.

possible yes, but the biggest factor would be that each plastic door covers an antenna. the led flash covers the gps, the battery covers the wifi, and the bottom door covers your cellular antennas. So replacing those with any kind of metal would connect them to the outer shell and ground them, almost completely shielding your phone from signal.
I just looked at the antenna except of gps (didnt want to open it all up). Wifi is just simply spaned mabe same with GPS. Only antenna that runs a bit through the door is the Sim/SD Door Antenna but if you would take a pretty flat and small cable you could run it through the left hole beside the two connectors. I dont know much about antennas but this could even make a stronger signal doesnt it?
p.s. The hole i mean is a bit upper left the two connectors (phone up side down)

the simple answer is no. antenna length is specific to the frequency it uses.
I understand you need a specific lenght of the antenna for certain frequenzies. So the cable that would be needed to connect the two connectors should have around the same lenght as the the Antenna in the plastic door.
Do you know how accurate this would have to be and how do they realize to use different frequenzies with one antenna GSM around 900 MHZ and WCDMA around 2,1 GHZ?
Anything can be done the real question is how much are you willing to spend?
And is it really worth the trouble to go through trying to fix it?
You should just get a new phone instead of changing the parts.

Replacement Speaker covers?

Looking to mod my N6 and since the speak er covers look the same as the Moto X I was wondering if it was possible to get new ones from anyplace. Preferably silver.
None?
Just trying to get some more opinions on this. I'd still like to find some.

It is possible. As shown on the attached photo of my Moto X, I have installed Nexus 6 speaker grills to achieve an all-black front fascia. The grills are interchangeable and can be removed by simply wiggling the grills until they become loose. The difficult part is finding the grills themselves.

I acquired some nexus 6 speaker grills through an unsavory method and was able to put them on my Moto x. The issue is the clips are slightly larger on the nexus 6 grills, so I got it to fit, stay put, and appear flush to the screen by sanding down the clips so they just fit inside the holes on the phone, then applying a tinyyyy amount of krazy glue just to the tips of the sanded clips so they stay put. Doesn't effect sound quality or anything, and looks great. Also tested to confirm they can still be pulled off with a little bit of force, but the excess glue may stop you from re applying the old grills in those spots, so beware of that, it seems like a permanent mod.

When you say unsavoury what exactly do you mean? I lost one of the speaker covers from my Moto X and I ordered some replacement ones but for the time being I'm using the ones taken from my friends unused Nexus 6 and they fit perfectly.
I would guess by going to att or someplace like that and taking it from a display model.
